I'm considering getting a set of fifteen52 Tarmac wheels. I have a few questions about what size to get for the fitment I want. I really want the face of the wheel to be flush with the fender. They have them in either 17" or 18" and anywhere from 8" to 9.5" wide.

Can I fit a 18" wheel on a 2010 Focus? Tire Rack provides a tire size for an 18" wheel for the 2010 Focus on their website.

Does anyone know how wide of a wheel I can fit or if I can find a tire that will fit that wide of a wheel?

Should I just get the narrowest wheel and then install home wheel spacers?

Anyone ever taken any measurements similar to what I am looking for, e.g. from hub mounting surface to fender?

Actually, I just checked their site again and the only size they have in 4x108 bolt pattern is 17x8, but it is offered in 35 or 42 offset.

I wouldn't know about the measurements or any of that, but I wouldn't go with any bigger than 17" wheels for two reasons 1). Your turn radius is affected & 2). The bigger the wheels the heavier they are, affecting not only fuel economy but also your speed sensor which would need to be calibrated for the new size. I wouldn't wanna bother with all that.

I was worried about turning radius. I have a tuner already so I can adjust the speedometer through that.

My ST3 has 18's & the turn radius is worse than my dad's F-450

wider wheels

300 miles on my new 2014 titanium HB and want to change wheels. Will keep the front size of 18x8, but want the rears to be 18x9. Very difficult finding a manufacture of staggered wheels with affordable pricing. Bolt pattern is now 5x108 (4.25) and this also creates another problem of adapters. Very difficult an operation for fitment, size, spacing and tires. With rolling the fenders there seems to be space for all this, but will take more then my little knowledge to make it happen. Would appreciate any opinion--

Fifteen52 has 18x8.5 and 18x9.5 wheels, just buy two of each size. Check out watercooledIND as well, should have the size you are looking for.

I see you have more than one thread on the same subject. Any how..... I commented on your other but this seems to be getting more attention.

What's the backspace and offset?

Offset is usually on the back of one of the spokes. Backspace can be measured by laying the wheel on its face lay something flat like a ruler on the back of the wheel and measure from the center hub to the ruler.

I actually made that thread to get a more direct answer because I have a couple questions in this one. I don't know what the backspacing is, but they are available in +15 to +35 offset. They are watercooledIND cc10's. I was thinking about getting the +15 offest.

15 offset would be nuts, you'd be better off with 35. Remember the lower the number the more the wheel sticks out. Stock wheels are et52 to 49. I run 18x7.5 et45 on my first gen. they sit nearly flush.

Focus MK1 RS wheels are 18x9 et42 they require fender work to fit on a 1st gen focus that's lowered.
